Ideal Heating published an installer update on 13 March 2024 to the customer safety notice it first issued on 1 February 2024, covering a product safety upgrade for boilers manufactured between August 2022 and 7 January 20241.
The notice states that in a small proportion of the affected range, approximately 1 in 10,000, "if an excessive volume of air has become trapped inside the boiler in a fault condition, it could cause the boiler to overheat and fail"1. The affected ranges are listed as Logic Combi2, Logic System2, Logic + Combi2, Logic + System2, Logic MAX Combi2, Logic MAX System2, iMini2, Independent Combi2, Keston Combi2 and Keston System21. Boilers in current production are not affected1.
| Item | Detail |
|---|---|
| Boilers affected | Manufactured August 2022 to 7 January 2024 |
| Ranges | Logic Combi2, Logic System2, Logic + Combi2, Logic + System2, Logic MAX Combi2, Logic MAX System2, iMini2, Independent Combi2, Keston Combi2, Keston System2 |
| Estimated rate | Approximately 1 in 10,000 |
| Engineer visit time | 30 to 60 minutes |
| Advised pressure | 1.5 bar |
The upgrade adds a component to the boiler, installed by an engineer, described as "an additional safety device" that Ideal says will not affect performance or efficiency1. The visit takes 30 to 60 minutes1. Customers are asked to register their details at www.idealsupport.co.uk or call 0808 175 9173 to arrange an engineer visit1. Ideal states it is directly contacting everyone who has registered the warranty of an affected boiler1.
"we can now inform customers we will be rolling out the product safety upgrade from the end of this month"
The notice also advises that boilers should be repressurised to 1.5 bar, and says customers can continue to use their boiler in the meantime1. Where a pressure gauge already reads 1.5 bar or above, the notice states there is no need to repressurise, though bleeding radiators may cause the pressure to drop, in which case it should be returned to 1.5 bar1. Ideal says it is aware of content circulating on social media about an incident which remains under investigation1. No detail of that incident, and no figure for the number of boilers affected, has been reported1.
Why it matters for households
For a household with one of the listed Ideal boilers, the practical effect is a booked engineer visit and a short interruption, not a replacement. The fault condition described depends on air becoming trapped inside the boiler, which is why the pressure advice sits alongside the upgrade: a system held at the correct pressure is less likely to reach that state. The added device is a backstop against overheating rather than a change to how the boiler heats the home, so running costs and efficiency are stated as unaffected1.
The wider point is about how a household knows what equipment it has. The affected list spans combi and system boilers sold under several names, including Keston, so the model name on the casing is not by itself a guide. Registration of the warranty is what puts a household in line for direct contact, and the notice relies on that route. For anyone weighing carbon monoxide and heating safety more generally, this notice concerns overheating and component failure rather than combustion, and the two are separate matters.
What happens next
Ideal Heating states the safety upgrade roll-out begins from the end of March 20241. Households arrange a visit by registering at www.idealsupport.co.uk or calling 0808 175 91731. The notice gives no completion date for the programme, and no further update has been reported1.
